Can home EEG use fewer electrodes without missing seizures?

Data: CHB-MIT · PhysioNet

The Big Idea, in Plain English

People with epilepsy can wear an EEG headset at home that watches their brain for seizures and can call for help. But hospital-grade EEG uses about 21 electrodes — expensive, bulky, and a hassle to set up. MYTER asks one simple question:

“Can we use far fewer electrodes and still catch the seizures?”

We built a program that reads the brainwaves, learns what a seizure looks like, and flags them. Then we compared a full 21-electrode setup against a cheaper 8-electrode one on the same real patient recordings.

What we found:

✓
8 electrodes caught the seizures about as well as 21 — a cheaper, simpler headset may be enough.
🧠
It learned the real signs doctors look for — certain brainwaves and spiky activity — not random noise.
⚖️
We tested it honestly. Small sample, so it's promising evidence — not final proof.

How It Would Work for a Real Person

  1. Wear the headset. A lightweight band with a few electrodes on hairless spots (forehead, behind the ears).
  2. It watches quietly. You don't keep an app open — it runs in the background.
  3. It detects a seizure. Your phone gets an alert asking “Are you OK?”
  4. You respond, or it escalates. Tap “I'm OK” to dismiss. No response + ongoing seizure → it notifies a caregiver, then emergency services, and shares your location.
